Magnolia Scale: What is It?
It is probably a fungus based on its name and appearance, and it kills trees by eating them. Upon maturation, female insects move little; they remain stationary on the branches.
The honeydew they produce can be found on our plants, homes, and cars, allowing molds such as sooty mold to flourish.
Upon maturation, it reaches a length of 1/2 inch, making it an enormous soft-scaled insect in the world. Trees can lose a large amount of sap through a plague, causing them to lose yellow leaves, dead branches, stunted growth, and even death.
A waxy matter is secreted over their bodies to defend themselves. The males, which are approximately 1/8″ long and white, look similar to microscopic flies. They are also smaller and more active than their female counterparts.
When crawlers are still in their early stages, they are called crawlers after emerging from their mothers’ bodies. They eat and multiply on tree branches during the winter.
It is much more effective at this stage to use insecticides than it is once they have matured. While the young are still developing, it is wise to target them. In adult males, their color lightens, but their size remains about the same. Shortly later, they breed, die within a few days, and cause slight damage.
Bugs that grow large, attach themselves to trees, and eat sap differ from females. They are white at first, but their color has transformed to a purplish-brown hue by the end of July. It will be August or early September before the crawlers emerge from their mother’s body.
So, many gardeners check their trees in autumn to see if they have insects attached to them. But, the trees are only covered in old insect shells.
